Hi,
I've been working.
And to work is to not write blog.
With this foreword I'll get to my next subject: retrospective. The word "retrospective" comes from latin word "retrospectare", which means to look back. It is the most important thing in becoming better on what you do. To become an expert one has to reflect experiences to teachings, measure what has been learnt, contemplate what should be kept or avoided and how to proceed to upcoming challenges. That and more is what we do in retrospective mode.
